Nice work, Aluminium bronze can be be quite challenging to cast. I am wondering if you did a vertical cast of that dagger if the shrinkage can be avoided

Agree, this application would respond better with vertical cast.

My hacksaw and files just skate across aluminum bronze. I have to use abrasive wheels to cut that stuff. Good looking blade! Oh and I finally subbed ;-)

swdweeb That’s what I experienced as well. It’s very strange to file and cut. Glad you enjoyed it!

Redditors can suck it for generalizing bronze then.

46 year machinist here, you need a new file and hack saw blade. No bronze is harder then a file. A file can cut toolsteel up to 45 Rockwell.

I love aluminium bronze. It's the first alloy that I made myself. It is super hard and takes a magnificent polish. Also, different component ratios have different colours.

If you add a pinch of silicon to your mix, it may help with flow and shrinkage.

4000 series aluminium would help.

I once had a job cutting up some old British Navy bronze stuff we tried Diamond and carborundum blades 9" and 12" we couldn't touch it, I noticed you were using a hacksaw on that I always wondered what mix the British Navy used for their bronze props and bearings it was a sight harder than rebar.

What? No bronze is nowhere near that hard. Rebar is 1014 hotroll steel.

watching you make the aluminum bronze dagger was fascinating :)

solve shrinkage problem with vertical casting?

Really great video! Love your work🤜🏼🤛🏼🇦🇺🍀😎

Gorgeous.

Look's AWESOME 👍🏻👍🏻👍🏻👍🏻

Fascinating!

Wow! Really impressive!

Turned out great.

you could have hammered a bit the edge before filing, aluminum bronze hardens with hammering... also maybe if you wanted it more yellowish you could have used 92% copper 8% aluminum, or even 92/6/2 Cu/Al/Ni (which is common for some coins)

Juan Pablo Alvarez Alfaro Thanks, I’ve tried hammering some of my blades and so far I have really just messed them up.

Very nice. Successful in my opinion.

Keep it up!

SALT PROOF Yes it would!

Aluminum bronze, less than 8% aluminum if you want to cold work it, and it is malleable and ductile. Over 8 % becomes very hard.

Sweet!

Wow no power tools - nice job 👍🏻

Very interesting

re patination have you tried making a ferric nitrate soloution and dipping the handel whilst hot?

I vent petrobond sometimes, but when I do I push my vent wire down through the cope with the pattern in place but stop about 1/4" above the pattern. If you just want to let the air out you can just put an open riser at the end, but to let gases out the non-contacting vents will work. They won't work if they're filled with metal.

Thanks for the suggestions. Lately I have found that petrobond really doesn’t need much venting. I get away with a lot without any vents at all.

Is that based on 2000 bc anatolian daggers? Totally enjoying your casting videos especially the historical ones.

Have you made a composite bow or ancient Egyptian arrows?

Michael Leeman Thanks! I don’t remember the number but it’s 7”x 9”.

I would have been tempted to grind dimples on both sides to create symmetrical dimples. For a dagger, I love the idea of having a more impact-resistant alloy.

So, normaly can take some plastic, cut out some form, which i need, dig in sands and cast??? so simple will be works?

that is a sick forge. how did you get your hands on the keg?

do u know what the specific alloy or the tin content/percentage is of those two tin bronze examples you showed?

Aluminum and its alloys tend to make much better hilt materials than blade materials

Would preheating the mould somehow reduce shrinkage?

How about adding just a -little- bit of phosphorous/copper to the bronze to inrease fluiity?

This!

I'm guessing the white powder you added was flux. What kind did you use? Great video!
